Cmake 2.8.7 does not find Perl libraries

[Darryl Pierce]

For any Cmake project that depends on Perl Cmake is not finding the Perl libraries even when they are installed.

The FindPerlLibs.cmake module asks Perl for the name of the library file using:

perl -V:libperl

which returns the name "libperl.so.5.14.2" as the name. And this file exists in in /usr/lib. However, the FindPerlLibs.cmake module tries to find it in:

    /usr/lib/perl5/${PERL_VERSION}/${PERL_ARCHNAME}/CORE
    /usr/lib/perl/${PERL_VERSION}/${PERL_ARCHNAME}/CORE
    /usr/lib/perl5/${PERL_VERSION}/CORE
    /usr/lib/perl/${PERL_VERSION}/CORE

instead. However, if the file libperl.so were to exist (I tested with a symlink) in one of the above mentioned directories (I used /usr/lib/perl/${PERL_VERSION}/CORE) then Cmake would find it just fine.

PROPOSED SOLUTION:

Symlink the provided libraries into the /usr/lib/perl/${PERL_VERSION}/CORE directory so that Cmake can find them.
